摘要
南京地铁二号线新街口站拟采用便桥疏解交通,便桥结构采用“321”装配式公路钢桥。为了保证便桥的可靠程度,需对所选用的贝雷粱,进行静力加载试验。通过试验研究其在不利工况下的应力和位移(挠度),试验结果表明所设计的桁架能满足工程要求,为工程实践提供了实践和理论依据。
Xinjiekou station of Nanjing No. 2 metro will solve the problem of traffic by the temporary bridge, whose framework is a ＂321＂ assembled steel highway bridge. To keep the structure safe, the static loading test has been done on the bailey beam. Having studied the stress and displacement （deflection） in the disadvantage cases, the test results have shown that the designed truss meets the demand, and it also provides practice and theory for the engineering practice.
